As an increasing number of workers return to the workplace, not everyone is eager to get back. Building air safety remains a concern in light of the COVID-19 pandemic. Even before current variants became known a reluctance to go back to the office existed. In fact, according to a study conducted earlier in 2021 by […]

Effective air filtration is key to maintaining good indoor air quality. In fact, you could say that an HVAC system is only as good as its air filtration system. The main function of the filtration system is to keep heating and cooling coils dust- and dirt-free, but it also works to limit chemicals, gasses, and […]

We might think we are safer inside than out when it comes to breathing dirty air but the fact is, that indoor air is oftentimes much more polluted than the air outdoors. The risk of airborne virus transmission is also greater and the COVID-19 pandemic highlights the need for higher IAQ standards. Of course, the […]

The U.S. has not faced a public health crisis like COVID-19 in over a century. Back then we did not have the mechanical systems we have today. This presented a new challenge for school building engineers. Many HVAC systems required maintenance and updating and some of the air quality measures now required were not supported […]

As the COVID-19 pandemic continues its hold on world health, the emergence of fungal infections has the scientific and medical communities concerned. Pulmonary Aspergillosis is chief among them. At Pure Air Control Services, we cautioned building managers about the dangers of this infection long before the SARS-CoV-2 outbreak occurred. In fact, we talked about the […]

  One might think that rapid air changes would be a good way to dilute the SARs-CoV-2 virus and prevent its spread throughout a building. While this seems intuitive, new studies show this isn’t the case. In fact, rapid air changes spread the virus from the source at higher concentrations. Within 30 minutes of an […]

Given what we know about the aerosol transmission of the COVID-19 virus, indoor air quality has never been more important. As a result, a building’s HVAC system remains an essential part of creating and maintaining healthy indoor air. You can think of an HVAC system as the lungs of the building only in reverse. The […]

  We’ve learned a lot about the SARS-CoV-2 virus over the past year. For example, we know that the virus spreads more easily indoors. We also know that improving ventilation reduces viral particle concentration. This lowers the risk of building occupants inhaling these particles or coming in contact with them on hard surfaces. Better ventilation […]

Every day we take more than 3,000 gallons of air into our lungs. We do this with 12 to 15 breaths every minute which translates to roughly six million breaths per year. For this reason alone, we should care about the quality of the air we breathe. Building managers should know this and the recent […]
